HONG KONG: As far as rocks on any planet go, this formation looks fascinating. But it’s even more fascinating to know that this particular rocky outcrop was photographed on Mars by NASA’s Curiosity rover and it holds further clues to the red planet’s wet past and, potentially, Mars’ habitable potential.
Currently studying the “Pahrump Hills” region at the base of Mount Sharp in the center of Gale Crater, this new view snapped by Curiosity on March 18 shows a work site Curiosity’s mission scientists call “Garden City.” This area is interesting as it shows two-tone mineral veins protruding from the surrounding rock.
The tough mineral veins were formed in Mars’ ancient wet past and they are sticking out of the rock up to 6 centimeters (2.5 inches) high. This means that the veins formed within the rock and the softer surrounding bedrock has since eroded away.
When comparing the geology of this particular area with the rocks that Curiosity has analysed in lower sections of Mount Sharp, a story emerges Mars’ ancient geological history.
